In this situation, refreshing the page will solve the problem (Not sure if this is the bug of Webstorm or not). In practice, I found that the breakpoint is not work when the first time page is rendered. Search: Intellij Remote Development Like Vscode.

#WEBSTORM DEBUG REACT CODE#
In latest version of Webstorm, debugging the code of a React project is as easy as debugging JS code in normal html pages (thanks for the sourcemap, the debugger can recognize breakpoints in the code before pre-compiled by Babel). So why not just debug the /tmp/myscript.js file with the same argument? Debug React project
The simplest way to debug the code in subprocess is getting the arguments of the subprocess and running the subprocess independently with the arguments.įor example, in above example code, the subprocess execute the Javascript code in /tmp/myscript.js with argument start. If you don’t want to see any new Chrome windows, use the Chrome Headless mode. When you initiate a debugging session, WebStorm starts a new Chrome instance and attaches to it. You can also use DevTools together with WebStorm. The console is the good, older way to debug web-based applications, and it still applicable today. In debugging React Native applications, WebStorm relies on the Chrome runtime, which is used by React Native itself. If your application uses Expo, clear the checkbox because this. Choose whether you want WebStorm to build and launch the application for you: Select the Build and launch checkbox if you are launching your application for the first time or if you have updated its native code since the last run. You can leave messages and display values. The Run/Debug Configuration: React Native opens. Just like subprocess.Popen in Python, Javascript cannot debug the subprocess directly. In JavaScript, console.log() is the de facto approach for logging messages. Specifically on Travis-CI, this can reduce test execution time in half. What should I put to the REACTDEBUGGER Env. Another alternative to expediting test execution time on Continuous Integration Servers such as Travis-CI is to set the max worker pool to 4. Hello ever since I upgraded my RN project to 0.50 and webstorm to the latest the debugger in webstorm doesn't work both for headless chrome and for node. There are some projects like create-react-app may use a third-party library cross-spawn to do the same things. with create-react-app) yarn test-runInBand. If you need the subprocess blocks the main process, you can use child_process.spawnSync instead. Also note the spawn function is an async function which will not block the rest code of the file.
The function accept a callback function and will call it when the subprocess is actually running and generate stdout texts.
